Pop star Billie Eilish to play Laneway sideshow

Billie Eilish has something special planned for those that didn't get enough of her at Laneway.

If Billie Eilish's Laneway performance isn't enough for you, the teen pop star has something special planned.

The American Bellyache singer will play a one-off all-ages post-Laneway show "as a gift to Laneway's Under 18 friends."

Eilish, 16, released her debut EP in 2017 and quickly gained attention for her dark take on pop tropes, with songs including Copycat and Ocean Eyes.

She's already played in New Zealand at the Tuning Fork at the end of last year, and that's where she'll play on January 30, the day after Laneway.

Tickets go on sale on Friday.
